Hi,

We are having issue with itsp sip trunk. We are able to send register request but right after registration completes with 3600 timer, right in next register message shows timer 0. And registration stuck. Here is the scenario.

ITSP-->Cisco 2811-->CUCM

I tried this thing with one other router as well but same issue happening. Further we got bug for same issue so upgraded to 15.1(4)M8 to 15.1(4)M10. But issue remains same.

We need to block second register timer 0 message. Kindly suggest. Configs and logs attached for reference.

For reference register request and register timer 0 shared below as well.
